Back shield 20 extends through the described opening being limited by described framework 21, and the edge incline of described back shield 20 cover the described framework 21 of part above.Described back shield 20 is around transverse horizontal pivot axis HH pivotable, so that described back shield 20 can at off position as shown in Figure 1, midway location by as shown in Figure 2 and until described back shield extends conventionally and described pick up case 12 on even keels moving between open position completely in line.As what can recognize, described pick up case 12 consists of plate independently, be pressed in a conventional manner and size by according to the size of other application and vehicle and difference.
Described back shield 20 is connected with described framework 21 by hinge 22, in an embodiment shown in, described back shield 20 moves between open position and off position by electrical motor 24.Described electrical motor 24 is controlled by the control unit 26 being arranged in described back shield 20 by the chaufeur of vehicle.
Described back shield 20 is fixed on its off position by lockout mechanism 28.As shown in Figure 3 and Figure 4, described lockout mechanism comprises a pair of lock bolt 30, by described back shield 20 carryings of contiguous each incline.Described lock bolt 30 has conventional structure, and has lymphogranuloma inguinale 32 and ratchet 34, and described ratchet 34 can be that the open position of opening moves to the off position that described ratchet 34 extends through described lymphogranuloma inguinale 32 from described lymphogranuloma inguinale 32.
Door bolt eye 36 is fixed in the inside face 37 of described lateral plate component 18, and described lateral plate component 18 and described lymphogranuloma inguinale 32 are in line.Described door bolt eye 36 has a pair of spaced bar 38, and the bar of its postmedian is set up and 32 engagements of described lymphogranuloma inguinale, and off position by described ratchet 34 together with described back shield around.Described ratchet 34 is controlled to be retained in latched position in common mode, relative motion between back shield described in latched position 20 and described lateral plate component 18 is suppressed, or be released by electric actuator (not shown), or manually, to allow described back shield 20 to move to described open position from described off position.As mentioned above, described lock bolt 30 is common, at this, does not describe in detail further.Electrical signal line 39 extends to control unit 26 from the sensor in described lock bolt 30, to indicate closing or open mode of described lock bolt.
Described lockout mechanism 28 also comprises a pair of Buffer Unit 40, similar each other between described Buffer Unit except pointer.The described back shield 20 that a pair of described Buffer Unit 40 is installed on contiguous described lock bolt 30 incline separately.Described in each, Buffer Unit 40 is connected with operating unit 44 by elastic force conveying member 41, the cable 42 that is sleeve 43 inside at this elastic force conveying member 41.Described operating unit 44 comprises electrical motor 46, by gear system 48, works, and with move operation bar 50 (as shown in Fig. 6 and Figure 11-13), passes through limited circular arc as shown by arrow A.Preferably, described driving device 48 is that self-locking arranges, worm drive for example, in the situation that do not have the application of power of described electrical motor 46 described control lever 50 can be maintained to needed position.Between a pair of forked support 86 of described sleeve 43 on described Buffer Unit 40 and described operating unit 44, extend.One end of described cable 42 is connected with described control lever 50, so as described control lever 50 be rotated in the translation that produces corresponding described cable 42 in described sleeve 43.
The other end of described cable 42 is connected with connecting rod 52 (Fig. 6 and Fig. 7), and described connecting rod 52 is pivotally connected to support 54.Deflection element with the form of tension spring 56 extends between described connecting rod 52 and pin 58 and connects from described support 54.
As shown in Fig. 7-10, described support 54 comprises a pair of spaced board component 60.The cam 62 with peripheral cam face 64 is arranged between board component 60, and by pivot pin 66 and each board component 60 pivotal joint.Described pin 66 is also connected described connecting rod 52 with described support 54, and described board component 60 is fixed on to the position relationship separating needing.
The track 68 of arc is formed on the bottom of described plate 60, and thru-bolt 70 extends through the track 68 of arc and by being formed at the groove 72 of described connecting rod 52 from described cam 62.Described connecting rod 52 is around the motion of described pin 66 thereby pass to cam 62 by described thru-bolt 70, so that described cam 62 rotates around described pivot pin.Thereby described spring 52 acts on and makes described cam 62 deflection facing one direction, and described cable can counteraction described in deflection, with by described cam to opposite spin.
Control stalk 74 passes through pivot pin 76 pivotal mounting in described board component 60, and has the afterbody 78 of the described cam face 64 of supporting.The relative one end carrying of afterbody 78 of described control stalk 74 has the bump rubber 80 with the elastic body 82 of end face 84.
Described control stalk 74 move through described afterbody 78 and described cam face 64 in abutting connection with being controlled by described cam 62.As shown in Figure 9, described cam face 64 little by little increases clockwise radius.Therefore, along with the fully anticlockwise direction rotation of described cam 62, as shown in Figure 9, described afterbody 78 meshes described cam 64 at maximum radius place, so that described end face 84 is extended by described support 54.Along with the fully clockwise direction rotation of described cam 64, as shown in figure 10, described afterbody 78 supports described cam face 64 at minimum radius place, and allows described end face 84 to be retracted by the extended position shown in ghost image line.Therefore, the rotation of described cam 64 by the position control of described bump rubber 80 between extended position and retracted position.Described camb contour is that the load applying by described control stalk 74 can not cause the rotation of described cam 64, so that described bump rubber 80 is maintained on needed position.
Described Buffer Unit 40 is arranged on described back shield 20, so that described end face 80 is arranged side by side with described D type post 19 sides.On this position, described bump rubber 80 can use pulling force to trend towards described in deflection back shield 20 away from described D post 19.
First consider the described back shield 20 being in a fully open position, can understand better the operation of described lockout mechanism 28.In this case, described electrical motor 46 is swivel lever 50, so that the pulling force in described cable 52 is removed, and described connecting rod 32 can move 8 around described pin 5 under the effect of described spring 56.Therefore, the fully anticlockwise direction rotation of described cam 64, as shown in Figure 9, so that described afterbody 78 is engaged at the maximum radius place of described cam face 64.Therefore, described bump rubber 80 is extended by described back shield 20.
In order to close described back shield, start order as shown in figure 14.Step 100, closing signal is controlled (not shown) by remote control equipment (RCE) or vehicle and is dealt into described control unit 26.Described control unit 26 is given described electrical motor 24 indication power supplys, so that described back shield 20 is rotated around described horizontal shaft HH.
When described electrical motor 24 lifts described back shield towards the position of closing, step 200, the signal of described control unit 26 responses " closing ", controls described electrical motor 46 and makes described joystick 50 anticlockwise direction rotations.The rotation of described joystick 50 is to transmit by described cable 42, and makes described connecting rod 52 around the deflection of the described spring 56 of its pin 66 rotation defence.The rotation of described connecting rod 52 causes that described cam 62 rotates accordingly, the radius reducing to described afterbody 78 to produce described cam face 64.Described back shield moves towards off position, and the idle running between described cam face 64 and the described afterbody 78 of described control stalk 74 connects the unsteady described pivot pin 76 of the described bump rubber of permission.The fixing described joystick 50 of described electrical motor 46 to maintain its minimum radius by described cam 64 during shutoff operation.
When described back shield 20 is near described D post 19, as step 300 indication, the described lymphogranuloma inguinale 32 of described lock bolt 30 meshes with the bar 38 of described door bolt eye 36, and unclamps described ratchet 34 around described bar.The described control stalk 74 that carries described bump rubber 80 can freely rotate around described pivot pin 76, and does not therefore resist the closing movement of described back shield 20.If described bump rubber 80 has rested on extended position during moving to off position, described end face 84 and described D post 19 in abutting connection with causing that described control stalk 74 rotates to retracted position around described pivot pin 76.
Step 400, along with the engagement in described door bolt eye 36 of described ratchet 34, signal sends to described control unit 26 by described signal wire (SW) 39.Step 500, according to the described lock bolt 30 of receiving with the indications of described door bolt eye 36 engagements, described control unit 26 signals to described electrical motor 24 so that described joystick 50 rotates and discharge the elastic force of described cable 52.When described joystick 50 rotations, the described cam 62 of described spring 56 rotation, impels described cam face 64 and described afterbody 78 engagements.Described control stalk 74 rotates until the described end face 84 engagement D posts of described bump rubber 80 around described pivot pin 76.The power of described spring 56 applies deflection between described back shield 20 and described D post 19, so that described ratchet 34 meshes with the described bar 38 of described door bolt eye 36.Described cam 62 depends on available space between described D post 19 and the described back shield 20 at lock-out state around the degree of described pivot pin 66 rotations, and described camb contour holds the subtle change in space.Along with the deflection between described back shield 20 and described D type post 19, suppressed at described lock bolt 30 and the described noise of fastening the relative motion quilt between eye 36 with a bolt or latch and having avoided snapping snapping.Spring deflection on described cam 64 guarantees that described elastomer block 80 constantly impels described control stalk 74 to resist described D post, to occupy any space and camb contour, stops load to discharge.
For described back shield is moved to open position from off position, described lock bolt 30 is discharged and 24 work of described electrical motor by described control unit 26, so that described back shield is moved to described open position.When described back shield 20 moves away from described D post 19, described control stalk 74 rotates under the effect of described spring 56 continuing, until be subject to described track 68 restrictions, and described bump rubber 70 is extended out from described back shield 20 completely.
From foregoing description, can draw, when described back shield 20 moves towards off position, described bump rubber 80 is restricted to from described extended position to the retracted position that can not suppress described back shield 20 and close.Once described back shield 20 is closed, described bump rubber 80 is moved to can provide the extended position of needed deflection between described back shield 20 and described D post 19.By this way, close the needed power of described lock bolt 30 and reduced, and the elastic force of described bump rubber 80 can suppress afterwards in locking the noise of snapping snapping.
Foregoing description supposes that the operation of described back shield 20 carried out by battery-driven car 24, and obviously, described lockout mechanism also can be applied in manually-operated back shield or other closure plates.Be used in manually-operated back shield, when described lock bolt goes out of lock, signal passes to described control unit 26 by described signal wire (SW) 39.Described control unit 26 signals to described electrical motor 46 so that described bump rubber 80 is retracted.When described back shield does not have when locked, described electrical motor 46 maintains retracted position by described bump rubber 80.Once described back shield is closed, the signal that completes locking can be in order to discharge described bump rubber.
Although the back shield at context-descriptive is used for vehicle, obviously, other closure plates of vehicle can be applied the similar device that conventional sealing is not provided in the exterior circumferential of described opening.
